But in fact, local diamonds really fall apart easily. For example, some are named "Angel's Kiss", "Swirl" and "Moonlight", or two-pronged inlaid styles, as well as inlaid diamond rings.
These diamond ornaments are very popular at present because of their novel appearance and smooth lines, and the inlay method adopted can fully show the unique optical characteristics of diamonds and highlight the aesthetic feeling of diamonds. But these diamond rings have very high requirements on technology. The imitation ability of China manufacturers is comparable. If a certain style sells well, it will lead to countless consumption, and we are not worried about whether we can grasp it well to some extent. Many manufacturers failed to meet the requirements and were repeatedly complained.
1. There are grooves on both sides. The setting method of double-groove single diamond requires high requirements for notches and grooves in notches. However, most products are either too large, with a small amount of inlays, or the inner notches are too shallow or vague. In addition, the edge of the groove is not tightly embedded in the edge of the crown, which makes the bracket and the diamond have poor fit and makes the diamond easy to loose and fall off.
2. Embedding method. Diamond rings are often inlaid by means of inlay, and the diamonds used are mostly small diamonds of 0.02ct to 0.06ct. In order to cover the diamonds as little as possible when making these diamond ornaments, most of the processing techniques are simply to make a small hole in the ring blank, put the diamond flat in the hole, and then squeeze the metal backing around the diamond with twist. The coverage area of a diamond crown is generally less than 65,438+00%, and the material on the back of the diamond is often thin and narrow, so it is difficult to see metal traces, which looks beautiful, but the three-dimensional effect of the inlay is gone, so the diamond can be said.
3. Double claw inlay. After thousands of years of development, the style of the ring is really difficult to express with novelty. Some styles are purely for innovation, often at the expense of other needs. Therefore, the congenital deficiency in design is also an important reason for the formation of diamonds. For example, in the so-called "Moonlight" series, the diamond is only inlaid with two claws, and the ring is weak. Although a small ring is added around the diamond pavilion, because there are only two claws at the stress point, once it is actually worn, it is easy to form a ring deformation and cause the diamond to fall.
